Caged area in a South Oak Cliff High School locker room where bare-knuckle fights between students were allegedly staged.

DALLAS - The Dallas school system was rocked by allegations Thursday that staff members at an inner-city high school made students settle their differences by fighting bare-knuckle brawls inside a steel cage.

The principal and other employees at South Oak Cliff High knew about the cage fights and allowed the practice to continue, according to a 2008 report by school system investigators.

"More than anything, I'm in shock and disbelief — shocked that this could ever occur and shocked that it would be condoned by a professional administrator," said Jerome Garza, a member of the Dallas school board.

The report, first obtained by The Dallas Morning News, describes two instances of fighting in an equipment cage in a boys' locker room between 2003 and 2005. It was not clear from the report whether there were other fights.

No criminal charges were ever filed, and there was no mention in the report of whether anyone required medical attention or whether any employees were disciplined. A district spokesman would not comment.

The allegations came to light during a grade-fixing investigation that eventually cost the high school its 2005 and 2006 state basketball titles. School officials were suspected of altering students' grades so that they could remain eligible to play for South Oak Cliff, a perennial basketball powerhouse in one of the poorer sections of the city.

The newspaper reported Thursday that Angela Williamson, a parent, said she was ignored when she attempted to bring the matter to the attention of district administrators after her son, Cortland, told her that students stood around clapping and screaming while watching a fight he participated in. He and another student fought for five to ten minutes in the cage in 2004. She said the students acted as if they were in an arena.

Williamson said she took her son out of the school and moved to another district shortly after he came home with a swollen hand.

"I said enough is enough, and we just left," she said. "This was the norm. My son said this is what they do — let them fight in 'the cage.'"

She said she met with a football coach who had encouraged the fights.

"He told me this is how they settled disputes in his day," she said.

In an interview with the Morning News, Donald Moten, who retired as principal last year, denied any fights were held.

"That's barbaric. You can't do that at a high school. You can't do that anywhere," Moten said. "Ain't nothing to comment on. It never did happen. I never put a stop to anything because it never happened."

In the report, a teacher was quoted as saying Moten told security personnel to put two fighting students "in the cage and let 'em duke it out."

The report said a hall monitor, Gary King, told investigators he witnessed the head of campus security and an assistant basketball coach place two students in the cage to fight.

Another hall monitor, Reno Savala, told investigators he came upon two students fighting in the cage "bare-fisted with no head or eye protection." Savala said the assistant coach was watching the fight and broke it up when Savala told him to.

"It was gladiator-style entertainment for the staff," Frank Hammond, a fired counselor who has filed a whistle-blower lawsuit against the district, told the newspaper. "They were taking these boys downstairs to fight. And it was sanctioned by the principal and security."

Hammond did not actually witness any of the fights, according to the report.

Garza, the school board member, said the board should look into whether criminal charges should be filed.

Dallas police said they have no record of any investigation by the department. The district attorney's office would not comment.

The allegations come about 10 days after law enforcement authorities reported that careworkers at a Corpus Christi institution forced mentally disabled residents to fight each other and recorded the brawls for their entertainment.
